fiPECIPICATION forming part of Letters Patent No. 371,384, dated October 11, 1887.

Application filed March 19, [887.

Serial No. 231,517. (No model.)

following, taken in connection with the accom panying drawings, is a full, clear, and exact description.

This invention relates to the ice-creeper for which I have obtained Letters Patent of the United States No. 340,378, dated February 19, 1886.

The object of my present invention is to proteet the foot of the wearer of the ice-creeper from the pressure of the spurs of the creeperplate when the latter is in its inverted position; and to that end my invention consists in the combination,with the creeper-plate and its pivot, of an attaching-plate provided with bearings for said pivot and formed with extensions or guards terminating with bearings for the spurs of the creeper-plate when in an inverted position,all as hereinafter fully described, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a side view of that portion of a rubber shoe to which my improved ice-creeper is applied. Fig. 2 is a detached plan view of the attaching-plate of the ice-creeper. Fig. 3 is an edge View of the same. Fig. 4 is a detached inverted plan view of the creeper-plate, and Fig. 5 is a plan view of the blank from which the aforesaid attaching-plate is formed.

Similar letters of reference indicate corresponding parts.

A represents the attaching-plate of the icecreeper provided with perforations for the reception of rivets, by which it is secured to the under side of the heel of the boot or shoe. Said attaching-plate I form of a blank of sheetsteel or other suitable sheet metal of the shape of an elongated plate having longitudinal incisions Z 2, extending from one end toward the opposite end and a sufficient distance to form a spring-tongue, t, between the ears 6 e, on which the creeper-plate B is pivoted, said ears being formed on the side portions of the plateA by bending said portions of the plate into small loops, as illustrated in Fig. 3 of the drawings. The creeper-plate is formed with a heel projection back of its pivot, by which projection it presses upon the spring-tongue t, and is thus forced to lie with its free end normally in proximity to the attaching-plate, and partially in both its operative position and inverted position.

The attaching-plate A is of sufficient length to form between the incisions Z Zan extension, t,

of the spring-tongue 2, which extension ter-- minates with the guards or bearings b bin such relative positions as to cause them to be interposed between the bottom of the boot or shoe and spurs of the creeper-plate when the latter is in its inverted position, and thus pro teet the wearer of said boot or shoe from the pressure of said spurs. By the aforesaid incisions the side portions of the attachingplates are also formed with extensions aa, which terminate with the guards or bearings a a, adapted to receive the pressure of the spurs of the creeper-plate when in its inverted position, and thus further guard against the injury of the foot of the wearer by the pressure o'fsaid' spurs.

I do not wish to limit myself to forming the described guards on all of the aforesaid portions of the attaching-plate A, inasmuch as the metal of which the said plate is formed may be sufficiently stiff to afford the desired protection by the formation of only one set of guards, either on the tongueextension t or on the extensions a a of the side portions of the plate.

Having described myinvention, what I claim as new, and desire to secure by Letters Patent, 1s

1. The improved ice-creeper, consisting of an attachingplate, a creeper-plate hinged on said attaching-plate, and guards on the latter arranged to be interposed between the bottom of the boot or shoe and spurs of the creeperplate when in an inverted position, substantially as and for the purpose specified.

2. In combination with the creeper-plate and its pivot, the attaching-plate provided with bearings for said pivot and formed with extensions a a, terminating with bearings a a for the spurs of the creeper-plate when in an inverted position, as set forth and shown.

3. In combination with the creeper-plate and its pivot, the attaching-plate formed with the ears 0 e, and with the spring-tongue t, and

tongue-extension t, terminating with bearings 21' b for the spurs of the creeper-plate when in an lnverted position, substantially as set forth county ofOnondaga in the State of New York, this 17th day of March, 1887.
